Abstract: PURPOSE:To ensure a connection with a normal method for an idle circuit at a time point of connection based on a route decided during the reservation, by reserving both the route and the time of a communication circuit between the decided air and ground only by the presence or absence of each trunk circuit at the corresponding time. CONSTITUTION:At a reservation center 70, the information on a reservation of communication between terminals 60 and 61, for example, is supplied through a reservation information input terminal 76. Thus a reservation collating device 78 reads the contents of a terminal storing condition file 71, a route selection file 72 and a circuit reservation condition file 73 respectively and then checks whether a communication circuit necessary for the time of the communication newly reserved is occupied by another reservation. If an idle circuit exists, a permission for reservation is informed through a terminal 77. Then the prescribed information and the reserved trunk line are written into the files 71-73 as well as to an operation file 74. A circuit control signal genertor 75 sets up the communication lines of terminals 60 and 61 at the time reservation via repeater stations f10-f40 and based on the information of the file 74.

Abstract: PURPOSE:To perform accurate judgment as to whether a medium is deformed in the conveying direction or not by measuring the difference between the passing length when the medium is pushed and conveyed and the passing length when the medium is conveyed under the state wherein the medium is not pushed. CONSTITUTION:When it is judged that the rear end of a medium has passed through a sensor A, a photodetector 11 receives the light from a light emitting element 10. The signal at this time is inputted into a counter 21, and the counted value n1 is stored in a memory device 23. Furthermore, when the conveyance of the medium progresses and the rear end of the medium has passed through a sensor B, a counter 22 is stopped in synchronization with the reception of the light with a photodetector 13. The counted value n2 is stored in the device 23. The n1 represents the passing length for passing the sensor A when the medium is conveyed under the pushed state. The n2 represents the passing length for passing the sensor B when the medium is not pushed and conveyed. The difference between the counted values n1 and n2 is operated. When the difference is within the preset allowable difference, it is judged that the medium is not deformed. When the difference is large, it is judged that the medium is deformed in the conveying direction.

Title: Electromagnetic relay
Inventor: NAKAGAWA MASAFUMI
IPC: H01H50/04
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To provide an electromagnetic relay in which a malfunction hardly occurs by forming recesses on a positioning face along partition lines defined by the armatures. SOLUTION: A cover 4 is molded integrally with the first and second armatures 2, 3, which are accordingly welded to their opposite pieces 4b and a center piece 4a near the opposite pieces 4b, thereby forming partition lines 4d for partitioning a positioning face 4c of the center piece 4a. In the cover 4, grooves 4e are formed along the circumference of the positioning face 4c in such a manner that the thickness of the center piece 4a is locally reduced. Since the groove 4e is formed along the circumference of the positioning face 4c, it also serves as a recess 4f along the partition line 4d. With this constitution, molding burrs (S) generated in molding intrude into the recesses 4f (4e) formed along the partition lines 4d defined by the armatures 2, 3, to thus position the positioning face 4c in secure abutment against a permanent magnet, thereby achieving a secure operation.

Title: Combustion chamber of 2-cycle engine
Inventor: TAKEYAMA TOSHINORI
IPC: F02B75/02
Filed: 1985-05-20
Abstract: PURPOSE:To enable reduction of the generation of noise from an engine through prevention of production of vibration of a piston, by a method wherein the center of the spherical surface of the inner peripheral wall of a dome is positioned closer to the ignition plug side than the top surface of a piston in the vicinity of a top dead center. CONSTITUTION:In a combustion chamber 8, the inner peripheral wall of a dome 9 is formed in a smooth spherical shape. A central point A of a spherical surface 13 is positioned closer to the ignition plug 12 side than the spherical surface of a piston in the vicinity of a top dead center, and located on axis X1-X1 of the ignition plug 12. This displaces a collecting spot of reflecting waves produced as a result of a part of pressure wave, produced by combustion, colliding with the inner peripheral wall of the dome 9, in relation to the top surface of the piston. Further, since the opening of the dome 9, positioned facing the plug, is slightly narrowed, the dome is prevented from exposure to the pressure of the reflecting waves, and besides, a range, in which a pressure is exerted on the interior of the dome 9, is decreased, and thereby impact exerted is reduced to prevent production of vibration of the piston itself.

Abstract: PURPOSE:To perform highly accurate exposure by varying the cross-sectional area of an electron beam and the electron-beam current density so that the product of the varied cross sectional area of the electron beam and the electron-beam current density on a specimen is approximately constant, and keeping the electron-beam current in the vicinity of the optimum focus. CONSTITUTION:The cross-sectional area of an electron beam is formed so as to have a magnitude corresponding to a pattern Q1 by using masks M1 and M2, a lens 3 between both masks, and a pair of deflectors 5, depending on the command from an electronic computer 4. In this case, a bias power supply S2 is controlled by the command 4, and an electron-beam densiy on a specimen 7 is set at D1. Furthermore, the excitation of a lens 6 is controlled 4 so that the electron beam is focused on the specimen 7 at a current value corresponding to the product of the cross sectional area of the electron beam and D1, and the pattern Q1 is described. Thereafter, the electron beam density is varied in response to the cross sectional area of the electron beam, and the beam is projected so that the product of the cross sectional area and the electron beam current density on the specimen is always kept approximately constant. In this constitution, since the electron beam having almost no blur is projected on the specimen without the readjustment of the projection lens 6, image description can be performed at a constant resolution, and the resusltant highly accurate exposure can be accomplished.
